that totally depends. if you're into "female orgasms" as seen in porn, which technically is just female piss, your penis would surely be quite radioactive, as the radioactive tracer molecule used in this exam gets excreted via the kidneys.
for your own radiation safety, i'd recommend anal sex and an umbrella.
of course this was done by Ukrainians haven't you learned from Chernobyl (please excuse me if i got the wrong race cause this applies for any race: DON'T FUCK WITH RADIATION)
@karmaGfa Surgery, driving, walking, drinking, and visiting your parents-in-law are also all considered safe but that doesn't necessarily mean that they are safe.
Love this video... you're hilarious and brilliant at the same time. Lol just saw the urine part hahahaha classic. I definitely need a gf JUST LIKE YOU, haha. Nice video, excellent work! :-)
das eluat kommt morgens "frisch" vom generator (Mo-99), der in der klinik steht. die aktivitaet wird dann gemessen, z.b. 5ml enthalten dann 3 GBq. die aktivitaet am ende des arbeitstages, z.b. 8 stunden, kann man dann entweder berechnen oder einfach nochmal messen - und je nachdem, wie viel man braucht, dementsprechend fluessigkeit aus dem eluat entnehmen. die untersuchung ist meist innerhalb von 30 minuten gelaufen (schilddruese), d.h. das ist kein problem.
Interesting that your salivary glands liked the stuff. You now have radioactive spit and, presumably, breath - just like Godzilla. Yea! Did you ever measure your saliva?
Oh dear! This video is getting better by the minute.
I 'like' most of your videos, but 8:00 had me LOL! and adding it to my favorites. People say I'm 'out there' at times, but I don't think I would/could do that. Funny how you keep saying 'disgusting,' yet you keep gathering more.. LOL!
when you hold the device an arms length away from you, you were still holding the device which makes it go off because the radio active stuff is flowing through your blood stream.
Oh and you are right, radioactivity is overrated. And since the nice TV ads, everyone thinks bacteria are the most evil critters around. And especially E.coli after the EHEC fever...I could go on and on. I'm pretty sure you exaclty know what I mean.
@gedankenwelten: That's not true. Just because radioactivity from Technetium isn't harmful doesn't mean that radioactivity from other elements can't cause serious harm. Cases in point are the Chernobyl and Hiroshima disasters.
Sure the media contorts lots of issues but there are things which are true as well. Better research and public engagement by scientists is perhaps a good solution.
@nvasistha I don't say radioactivity is harmless, but it's vastly overrated. Chernobly an stuff is so dangerous because aerosols of alpha radiating isotopes are generated. If you have a solid alpha radiator on your desk there is (usually) no big problem, the radiation only travels a few mm, but if you ingest, it's the other way around.
I don't want to go into a funny discussion, just trust me that I know what I'm talking 1. because I'm a nerd, 2. because it's part of my CTA education.
You are a lot more nerdy than I am, and I have slight Aspergers Syndrom.
The only things I have in my kitchen (besides angle grinder and other "kitchen" stuff) is supercooled CH3COONa * 3H2O, NaOH, NH3(aq), HNO3, NH4NO3, Alkohol, CH3COOH, a selfmade 8 inch telescope mirror and a selfmade photometer.
But I've yet to include a radioactive urine sample :D .
I know that Tc in males, tends to be drawn to the testes!!! (Seriously!) What effect in a female, I don't know. I take it you're having work for a thyroid problem? (Overactive?) Didn't know the thyroid absorbed it like radioiodine. You poor thing! get better soon....and find out more about technecium.
For its production are used Mo-99 from a research reactors
Although the Mo-99 is one of the fission product yield of Uranium, but it's technically easier is using Mo-98 (stable) and hit it by the neutrons. After the neutron capture: Mo-98 (n,γ) Mo-99
Mo-99 is in the isotope generator, called "MOLYBDENUM COW" (because it's "milked")
Saline solution (the ELUENT) of the 1st tank, leaches from Mo-99+Tc-99(m), only radio-Technetium & it accumulates in the 2nd tank (the ELUATE)
-> Because the activity of the Tc-99m = 1.9e 17+Bq/gram, and the activity of the Tc-99 = 6.3e+8 Bq/gram — so 70MBq of Tc-99m = physical quantity... 0.36 nano gram of Tc-99m!
-> While the all Tc-99m, turned into a Tc-99 — therefore, the activity of 70 MBq (70,000,000 decays per second!) rapidly fell to the faint 0.23 Bq (1 decay per over 4 seconds).
3:18 - The dosimeter shows 84.3μSv / h. Because the half-life of Tc99m is 6 hours, so day later (24 hours later = 4 half-life periods of Tc99m), should show a maximum of 1/16 the original value, etc.
So after:
00 h = 84.8μSv /h
24 h = 5.3μSv/h
48 h = 0.3μSv/h
72 h = 0.0μSv/h (ie 0.021μSv / h)
94 h = 0.0μSv/h (ie 0.001μSv / h)
...later, even less: pico Sv/h, atto Sv/h, etc.
(nobody, of course doesn't measure "such" units)
—> Does Madame, received similar results (higher / lower)?
the actual results are lower than that, as the biological half life of Tc-99m is very short. i dont know how short exactly off the top of my head, but the body basically doesnt have a use for the pertechnetate, so it quickly gets excreted... so you have to take both the physical half life (which you mentioned) as well as the biological (excretion) half life into consideration.
that will not work, as gamma radiation that can enter the chamber from the outside, such as from a technetium scintigraphy, will NOT produce any cloud tracks. only charged particle radiation (alpha, beta, proton) will produce visible tracks.
@bionerd23 — in the Cloud Chamber, allows you can see a γ-ray photons, but the effect of their impact is very delicate! Traces of the particles are much more stronger...
— a traces after influence of a particles, are shown as lines: thin long (β), short thick (α) — sometimes them at the end are bifurcated after scattering with air atoms
— a traces after the influence of γ-ray photons, it's usually short filamentous structures — these are traces of slow electrons scattered in the Compton effect
well, compton effect is most likely to occur in 0.2-10MeV photons, so it's pretty rare for Tc-99m gammas (141 keV) - but yeah, some compton electrons / conversion electrons / photoelectrons will be visible in the cloud chamber, that is true. just saying, you cannot view the photons directly, but only by their interactions.
@TypesElivAspieEyes LOL I think it's called something I am sure somewhere in professional texts if not there ought be a name for it. It's the fascination with things we ought to be or have been scared of. At 6 I was still terrified of vacuum cleaners! Then it broke. Realizing the cylindrical beast of my nightmares the monster was dead I took it apart & fixed it gave it new life I was a proud 6 year old boy vacuuming everything in sight, then it blew up! My mommy threw it away. I learnt respec
i think putting the collected cellular matter you produced there though HCL washes and a defatting process should clear it into a nicer compound lol. you could probably have sublimated Te from the liquid urine also.
one of my all time favorite videos... personally, I have used a ccd to record beta (Te99 ... check source, and alpha (Pu238 check source) decays , and it is glorious... thank you, for doing awesome things!
lol i like the video, but kind of wierd =/ towards the end, an Element Collection ???? "another face =/ ... i guess your excited to be radioactive lol. in the video towards 9:20 you said Tc99m half life was 7 yrs but its 6.01hrs. with a low energy of just 140 kev the Parent is Mo99m with half life of 66hrs
You're nuts, but I like you. Don't play around with this stuff for too long because, even though radiation is over-rated, the body still has its limitations.
Your ovaries are like miniature chromosomal damage testing facilities to produce 3 eyed monster babies with 6 fingers and a tail with enlarged encephalitus brains yet are still cute. Such cute babies. HEH
Es mag unproblematisch sein, Gammastrahler im Körper zu haben, aber viele radioaktive Stoffe SIND problematisch, weil sie eben Alphastrahler sind, von denen man eben wesentlich mehr Strahlung resorbiert und deren Strahlung wirklich große Schäden verursacht.
(Wenn ein Heliumkern (Alphastrahlung), also ein Edelgasatom ohne Elektronen(Elektronegativität~50), auf ein Molekül deines Körpers trifft, ist dieses Molekül hin, und wenn es ein DNS-Molekül war, viel Glück)
interessante Versuche die Du da machst! Aber zu Deiner Aussage dass Radioaktivität überbewertet wird: Das Problem ist einfach dass es schwer einzuschätzen ist. Dein Probe-Strahler kann recht harmlos sein, obwohl er gefährlich aussieht. Aber als ich in Neckarwestheim 2 am Abklingbecken stand hätte ich in einer Sekunde die tödliche Strahlung abbekommen – wenn da nicht das Wasser zwischen mir und den Brennelementen gewesen währe - Und auch das hätte ich nicht so eingeschätzt.
Radioactive pee boiled down on a stove?! Das Video für all die "Frauen gehören in die Küche"-Machos – danach wird dieser Spruch wohl nie wieder über ihre Lippen kommen ...
This sound of the Geiger Counter (or whatever it is) gives me chills! But i have to say that is a little bit annoying listening to it in a long period of time..
Hashimoto hat meine Schwester auch aber sie wurde noch nie bei einer Behandlung mit einer Technetiuminjektion behandelt. Ich frag mich grade was des bringt. Wird damit der grad Leistungsfähigkeit der Zellen in der Schilddrüse erkennbar oder wie soll man sich des vorstellen
genau - man kann den "uptake" feststellen, d.h. wieviel iod die schilddruese noch aufnehmen kann, wie aktiv sie noch ist (bzw. im umkehrschluss wie geschaedigt sie schon ist, bzw. ob sie ueberempfindlich auf iod reagiert). auch kann man knoten abgrenzen - selten treten bei hashimoto auch heisse knoten auf (hormonproduzierend, szintigraphisch ueberaktiv / "heiss" dargestellt); meist sind es kalte knoten (oft gutartig, aber manchmal handelt es sich dabei auch um krebs).
ahh cool Danke!! jetzt bin ich wieder schlauer ^^. Was ich mich so allgemein Frage hast du beruflich mit Kernphysik was zu tun oda is des bei dir reines Hobby. Ich sammle selbst diverse radioaktive Mineralien hab auch nen Geigerzähler ( keine Gammascout ^^) son altes russisches Teil namens Prypjat 20 03 oda so. Ich habe deine anderen Videos auch gesehen und mich verwundert bloss dein allzu lockerer Umgang mit dem ganzen zeug ich selbst schirme mein Sammlung mit 50 kg Blei ab ??
Did you consider any ways to further clean the sample you collected? If you need to do this again, I suppose you could be sure to keep plenty of clean water entering your system so the boiling off part is less nasty. :)
So, I can't find the answer, you had gamma scintigraphy procedure...why exactly? You're not sick are you? Also, 6:51 I hear you, totally agree about media making a huge deal about a wee bit of ionizing radiation, I can share with you my theory about why that is.
"sick"? no, sick sounds so much like feeling bad etc. - nope, i'm not sick. i'd say i have a "condition" called hashimoto's thyreoiditis, but i just take two little pills every day and replace my destroyed thyroid with those. quite simple, no side-effects, nothing to worry about.
@bionerd23 *wheatley voice* Fine...good...not sick is good...excellent in fact */wheatley voice* So, at a guess one is a synth thyroid hormone like maybe levothyroxine, and the other is....? Both subsidized by the state, I hope, or at least fairly inexpensive? I hope your immune system is tamed now, and doesn't get hungry for any more of your precious vital organs. Bad, bad immune system! =/
yup, i take both synthetic T4 and T3, due to an issue with conversion of T4 into T3. largely paid by health insurance. true, wouldnt want my immune system to attack an organ that i actually require to live, though, lol. then again, i heard rumors about people with allergies and autoimmune diseases - people with a highly sensitive immune system - are also less likely to get cancer, as the immune system is easier to detect malfunctioning cells and just kills everything. handy for me. :P
@bionerd23 It's an ill wind (or immune system) that blows no man (or bionerd) good. Handy for you as long as it stays away from your wiring. I bet your leukocytes have little turret voices. "Is anyone there?...Resting."
well, for all i know, i've been in direct contact with ill people (flu, cold, bronchitis, etc.) last winter and only twice caught a very mild cold during the past 12 months, which was basically affecting me a little for two days and was gone after about 4 days. never required me to stay home or rendered me unable to work, though. if i compare that to what other people around me had caught, i'm really glad for this immune system so far, lol.

2:44 - have a look at that picture. color represents amount of radionuclide present areas. sure, my body was radioactive basically everywhere, but you can CLEARLY see in that image that the thyroid gland (as well as e.g. salivary glands) take up the radionuclide MUCH better than surrounding tissue. the technetium-99m pertechnetate is highly selective for a few organs. same as 99mTc-2-methoxyisobutylisonitrile would be selective for the heart, with the thyroid being "cold".
There is this insect on the U-tube (somewhere). I have been wondering if this insect got a dose of radioactivity? The mutation cause some type of merge between a Wasp and a Grass Hopper. Really cool. The radioactivity may prevent cells from proper division. They may (theoretically) be cut and spliced back together with a large dose of radioactivity? It might explain how that insect came to be?
That Technetium has a half life of 60 days (Wikopedia). Radioactive Iodine, The bad isotope has a half life of 500+ years. This is an important distinction. I'm curious as to why they use something with such a high half life?
Hi Bionerd23, I have a question. I have the same geiger counter as you. But I did something stupid. I put my finger in te hole to clean the "collector" I made 2 movies. 1 on the graveyard: watch?v=Lp1p0fppEGE looks like its still working or is it not measuring correct anymore?
In de second video you can see the layer I removed a little with my finger :( watch?v=r9yFk-Zft60
My question is, does this device still work as intended? or did I broke it?
but yeah, it's true, i am a slut. i swing between technetium and caesium, strontium and barium... i'm not ever faithful to my uranium. i cant just love ONE nuclide. uranium is still my favorite, but i just love those cute little technetiums as well. -_-
@bionerd23 You are soooo funny :D I am a science geek and always had my weak point for radioactivity... I am planning on buying a Gamma-Scout.... :) When I had gammagraphy (of my kidneys) done I walked round and I was saying "Keep away, I'm radioactive" :) oh I was a silly child three years ago :).
@bionerd23 lol it shouldnt be called uranium, but urinium xD
Ja ich weiß das war jetzt Tecnetium, aber was solls, ich glaub ich muß mir auch mal nen Gamma-Strahler irgendwoher besorgen um damit zu experimentieren.
@bionerd23 lol it shouldnt be called uranium, but urinium xD

the gamma rays are very destructive to dna in a cell (depending if the exposure is chronic or acute), the dna serves as a code for cell replication, once the dna repair system failed and the dna is altered, the cell replication goes spontaneaous and crazy resulting to uncontrolled cancer cell replication...
Thanks a lot for this really interessting video! One of the best, I've seen on YouTube in a long time. And it was funny too: especially at 6:47, when you said "Radioactivity is very much overrated." LOL I just burst in laughter and it made my day. Thanks for it. :-D
Regarding your statement, well I guess it depends on the dosis ...
Wow! only a three day half life! That means that you have about 21 days to extract the stuff and only a few days per extraction! fresh From the reactor, indeed!
I am still amazed that such levels are not dangerous, though I realize they are gamma and short lived. I would have flipped out if I had been on that bus with my GM and detected 20uSv/Hr!!! I would have jumped out of the bus window. My self preservation impulse is set really high.
Well, that places my overactive fear in perspective. Lol. If He crazy radioactive tc iso only has a few hours of half life and about 7 halflives kill it, they must make it fresh for doctors quite often. Interesting.
it comes from a Mo-99 generator. but first things first; you use HEU (highly enriched uranium, 90%+) for a chain reaction that produces about 300 terabecquerel of Mo-99 per 500 grams of U-235 every 24 hours. then, you bind that Mo-99 (half life: ~3 days) into a generator. the Mo-99 is fixed into it, the decay product - Tc-99m - can be "washed out" using sterile sodium chloride solution, and is afterwards ready to use as Tc-99m-pertechnetate (the stuff i was administered). :)
Gamma-Scout Gmbh should thank you because your video reports made me buy their product!
Related, a brief question: I read in Wikipedia that Alpha particles resulting from decay only travel up to a few cm in air. How then, if at all, would it be possible for them to travel "all the way" up into the G/M-tube of the Scout, which is more like 5 cm long AND it's opening is approximately 1.5 cm recessed into the housing?
Many thanks for your good work and informative/entertaining videos!
well, they just need to get to the front of the tube - and they can travel for 1.5 cm usually, but the closer you get with an alpha source, the more counts you will register.
My mom was diagnosed with Grave's disease a week ago =(. They gave her 200uCi of I-123 (I was hoping for Tc-99m). Oh well. I got the empty I-123 test tube. I asked her if I could do the same thing you did, and she let me! My mom knows little about science, but she thought it was awesome! I did all the dirty work, but outside, because it's gross! It looked just like that! It's now stable, but I got it on camera. She's due for 16mCi of I-131 next. At least she got some good news out of that day...
so, when are you gonna upload that video to youtube? :D
be sure to tell me when you do!
i wish i had grave's disease as well. i'd love to document some radioiodine treatment. the disease is - due to the awesome treatment options - rather harmless. just destroy the thyroid and replace with hormones if necessary. might take a while to find the perfect dose of hormones for well-being, but apart from that, the procedure is completely harmless! all the best to your mum, anyway!
@bionerd23 XD funniest part 0:32- 0:36 she (bionerd) was like: your going to put that stuff in my blood...(doctor puts it near gamma scout).. and then she went OMG O_o XD ahhah lol awesome thing still :D
schönes wissentschaftlich dokumentiertes Video, iss aber alles halb so schlimm mit den Werten bei diesen Dosen, ich hab bei mir zu hause z.b. ein paar Urdoxe und Kaltkathodenröhren aus den 60ern, die kommen häufig in alten Röhrenradios vor (repariere gelegentlich solche), die haben meist so 80 bis 100 µSv/h, sind aber alles beta-Strahler, bewahre sie in Bleibehältern auf - haben mir übrigens alle gut gefallen Deine Videos bis jetzt mit radioaktivitäts-Inhalt, weiter so, klasse !
Technetium has a short half life, but you can't hold a counter to read other objects while you're radioactive yourself. Since it's a gamma emmitter, it passes through the case of the counter to reach the geiger tube. Long term radioactivity isn't over-rated as it alters DNA strands and causes genetic mutations over time. Hiroshima and Nagasaki proved this over several generations who still suffer the effects of the A-bomb. Today's generation of young people have learned nothing from it.
sure i can hold the counter while being radioactive myself; for semi-accurate measurements, i'll just have to substract the background dose i am producing. ;) e.g. if there's 3 uSv/h when i'm holding out my arm with the counter in my hand, and i am measuring 8 uSv/h on an object while maintaining the same position, i can estimate about 5 uSv/h to come from the object.
when i meant radioactivity is overrated i was referring to standard every-day life stuff, like x-ray scans or just the natural background radiation. i wasnt talking about the "extreme" things like nuclear bombs. depleted uranium ammunition is horrible, too... it's not the radioactivity, but it's a heavy metal, and the fine distribution of that ends up in ingestion of the heavy metal, which causes horrible toxic / mutagenic effects. would be same for e.g. cadmium as well, tho.
uranium (no matter which isotope) is a toxic heavy metal, just as lead or mercury, for example. if especially the fine dust usually produced by these ammunitions get into the food chain in large amounts, it's very bad for whoever and whatever consumes it, no doubt.
there are minor amounts of uranium in every water, as it's a natural mineral. however, when it gets TOO MUCH, it leads to horrible defects in humans (just as mercury or cadmium would, too).
foodwatch recommends no more than 5 micrograms of uranium per liter of water for the making of baby food. some waters here (germany; we have a lot of uranium content in the earth's crust in e.g. saxony) contain 40+ micrograms of uranium per liter of water, which could already be bad for children in theory - and that's STILL minor amounts and from natural sources...
How if the technetium-99 is injected directly into your blood stream does it target only your thyroid and not damage every cell in your body?.. and is this a 1 time only procedeur or will you have to do this again in the future as technetium99 only having a half life of 6 hours... and are you still radioactive? many thanks.
it does get into all of your body and gives you a dose of about 1 mSv. however, you can get the Tc-99m to target specific organs (so MOST of it will go there) by binding it into molecules that the organ takes up for metabolism. like, the pertechnetate (TcO4) "looks like" iodine, so the thyroid takes it up. the methoxyisobutylisonitrile (C36H66N6O6Tc) "looks like" electrolytes the heart wants to use, so it migrates to the heart.
the image is done within the first hour after injection; you have an image of the current state of the organ then, just as if you did an x-ray image of something. unless you need to check up on the organ for some reason, you do NOT need to repeat the procedure. the patient will be non-radioactive within about three days, with most of the radioactivity being excreted within 24 hours.
Hab gelesen, die allgemeine Strahlungsbelastung für normale Bürger sollte bei ca 4 mSv/Jahr liegen(2mSv/Jahr durch Natürliche Quellen und weitere Zwei durch Künstliche, bei Untersuchungen). Bei Zwei Tagen mit 1mSv/std ergibt das im Vergleich gewaltige 48 mSv in dieser relativ kurzen Zeit, also das 12-Fache dieser angegeben Jahresdosis. Da hätte ich dann schon Grund zur Sorge, wenn ich solch eine Untersuchung auch nur mehrmals innerhalb 10 Jahren durchführen müsste.
theoretisch schon, praktisch zerfaellt das zeug aber 1. sehr schnell (halbwertszeit 6 stunden) UND wird sehr schnell ueber die nieren ausgeschieden... insofern, wenn man nicht am technetium-tropf ;) haengt, betraegt die effektive dosis gerade mal 1 mSv.
when an atom decays (alpha / beta), the daughter nucleus is usually in an excited stage and thus, emits a gamma ray. in most cases, this happens RIGHT after decay (a few nanoseconds after it). however, in some cases, it takes longer for the gamma ray to emitted - and this is the case after Mo-99 decays into Tc-99. the newly formed Tc-99m atom takes an average (half life) of 6 hours to emit the y-ray. this is called a METASTABLE state, and that's what the "m" stands for. :)
so yeah, to sum it up, Tc-99m is the metastable state that has NOT yet emitted the gamma ray; the half life for the gamma emission to happen is 6 hours. Tc-99 is the ground state after having emitted the gamma ray of excitation energy from the Mo-99 decay, and it has a half life of twohundredthousand years. it then undergoes beta-decay to form Ru-99, which is stable (not radioactive).

@nvasistha I don't say radioactivity is harmless, but it's vastly overrated. Chernobly an stuff is so dangerous because aerosols of alpha radiating isotopes are generated. If you have a solid alpha radiator on your desk there is (usually) no big problem, the radiation only travels a few mm, but if you ingest, it's the other way around.
I don't want to go into a funny discussion, just trust me that I know what I'm talking 1. because I'm a nerd, 2. because it's part of my CTA education.

How to make Tc-99m?
For its production are used Mo-99 from a research reactors
Although the Mo-99 is one of the fission product yield of Uranium, but it's technically easier is using Mo-98 (stable) and hit it by the neutrons. After the neutron capture: Mo-98 (n,γ) Mo-99
Mo-99 is in the isotope generator, called "MOLYBDENUM COW" (because it's "milked")
Saline solution (the ELUENT) of the 1st tank, leaches from Mo-99+Tc-99(m), only radio-Technetium & it accumulates in the 2nd tank (the ELUATE)

@AndrzejKaron
nice explanations by the way, thank you for the valuable comments. =)
bionerd23 3 months ago
Tc-99m is obtained from Mo-99 (T½ = 66 h), which it decays into: Tc-99m (88%), and into: Tc-99 (12%).
Of course, the ISOMER: Tc-99m after the emission of a photon γ (T½ = 6 h), becomes also as Tc-99 - note: in this case, THIS IS NO DECAY!
However, Tc-99 is also radioactive, but with its T½ = 213 ky, it has so veeeeery lower activity than Tc-99m!
The Tc-99 decay into Ru-99 (STABLE).
AndrzejKaron 3 months ago
(continue)
-> Because the activity of the Tc-99m = 1.9e 17+Bq/gram, and the activity of the Tc-99 = 6.3e+8 Bq/gram — so 70MBq of Tc-99m = physical quantity... 0.36 nano gram of Tc-99m!
-> While the all Tc-99m, turned into a Tc-99 — therefore, the activity of 70 MBq (70,000,000 decays per second!) rapidly fell to the faint 0.23 Bq (1 decay per over 4 seconds).
AndrzejKaron 3 months ago
3:18 - The dosimeter shows 84.3μSv / h. Because the half-life of Tc99m is 6 hours, so day later (24 hours later = 4 half-life periods of Tc99m), should show a maximum of 1/16 the original value, etc.
So after:
00 h = 84.8μSv /h
24 h = 5.3μSv/h
48 h = 0.3μSv/h
72 h = 0.0μSv/h (ie 0.021μSv / h)
94 h = 0.0μSv/h (ie 0.001μSv / h)
...later, even less: pico Sv/h, atto Sv/h, etc.
(nobody, of course doesn't measure "such" units)
—> Does Madame, received similar results (higher / lower)?
AndrzejKaron 3 months ago
@AndrzejKaron
the actual results are lower than that, as the biological half life of Tc-99m is very short. i dont know how short exactly off the top of my head, but the body basically doesnt have a use for the pertechnetate, so it quickly gets excreted... so you have to take both the physical half life (which you mentioned) as well as the biological (excretion) half life into consideration.

@bionerd23 — in the Cloud Chamber, allows you can see a γ-ray photons, but the effect of their impact is very delicate! Traces of the particles are much more stronger...
— a traces after influence of a particles, are shown as lines: thin long (β), short thick (α) — sometimes them at the end are bifurcated after scattering with air atoms
— a traces after the influence of γ-ray photons, it's usually short filamentous structures — these are traces of slow electrons scattered in the Compton effect
AndrzejKaron 3 months ago
@AndrzejKaron
well, compton effect is most likely to occur in 0.2-10MeV photons, so it's pretty rare for Tc-99m gammas (141 keV) - but yeah, some compton electrons / conversion electrons / photoelectrons will be visible in the cloud chamber, that is true. just saying, you cannot view the photons directly, but only by their interactions.

Es mag unproblematisch sein, Gammastrahler im Körper zu haben, aber viele radioaktive Stoffe SIND problematisch, weil sie eben Alphastrahler sind, von denen man eben wesentlich mehr Strahlung resorbiert und deren Strahlung wirklich große Schäden verursacht.
(Wenn ein Heliumkern (Alphastrahlung), also ein Edelgasatom ohne Elektronen(Elektronegativität~50), auf ein Molekül deines Körpers trifft, ist dieses Molekül hin, und wenn es ein DNS-Molekül war, viel Glück)

Hi,
interessante Versuche die Du da machst! Aber zu Deiner Aussage dass Radioaktivität überbewertet wird: Das Problem ist einfach dass es schwer einzuschätzen ist. Dein Probe-Strahler kann recht harmlos sein, obwohl er gefährlich aussieht. Aber als ich in Neckarwestheim 2 am Abklingbecken stand hätte ich in einer Sekunde die tödliche Strahlung abbekommen – wenn da nicht das Wasser zwischen mir und den Brennelementen gewesen währe - Und auch das hätte ich nicht so eingeschätzt.

it comes from a Mo-99 generator. but first things first; you use HEU (highly enriched uranium, 90%+) for a chain reaction that produces about 300 terabecquerel of Mo-99 per 500 grams of U-235 every 24 hours. then, you bind that Mo-99 (half life: ~3 days) into a generator. the Mo-99 is fixed into it, the decay product - Tc-99m - can be "washed out" using sterile sodium chloride solution, and is afterwards ready to use as Tc-99m-pertechnetate (the stuff i was administered). :)

Technetium has a short half life, but you can't hold a counter to read other objects while you're radioactive yourself. Since it's a gamma emmitter, it passes through the case of the counter to reach the geiger tube. Long term radioactivity isn't over-rated as it alters DNA strands and causes genetic mutations over time. Hiroshima and Nagasaki proved this over several generations who still suffer the effects of the A-bomb. Today's generation of young people have learned nothing from it.

sure i can hold the counter while being radioactive myself; for semi-accurate measurements, i'll just have to substract the background dose i am producing. ;) e.g. if there's 3 uSv/h when i'm holding out my arm with the counter in my hand, and i am measuring 8 uSv/h on an object while maintaining the same position, i can estimate about 5 uSv/h to come from the object.

when i meant radioactivity is overrated i was referring to standard every-day life stuff, like x-ray scans or just the natural background radiation. i wasnt talking about the "extreme" things like nuclear bombs. depleted uranium ammunition is horrible, too... it's not the radioactivity, but it's a heavy metal, and the fine distribution of that ends up in ingestion of the heavy metal, which causes horrible toxic / mutagenic effects. would be same for e.g. cadmium as well, tho.

@defkon99
uranium (no matter which isotope) is a toxic heavy metal, just as lead or mercury, for example. if especially the fine dust usually produced by these ammunitions get into the food chain in large amounts, it's very bad for whoever and whatever consumes it, no doubt.
there are minor amounts of uranium in every water, as it's a natural mineral. however, when it gets TOO MUCH, it leads to horrible defects in humans (just as mercury or cadmium would, too).
bionerd23 1 year ago
@defkon99
foodwatch recommends no more than 5 micrograms of uranium per liter of water for the making of baby food. some waters here (germany; we have a lot of uranium content in the earth's crust in e.g. saxony) contain 40+ micrograms of uranium per liter of water, which could already be bad for children in theory - and that's STILL minor amounts and from natural sources...

it does get into all of your body and gives you a dose of about 1 mSv. however, you can get the Tc-99m to target specific organs (so MOST of it will go there) by binding it into molecules that the organ takes up for metabolism. like, the pertechnetate (TcO4) "looks like" iodine, so the thyroid takes it up. the methoxyisobutylisonitrile (C36H66N6O6Tc) "looks like" electrolytes the heart wants to use, so it migrates to the heart.

the image is done within the first hour after injection; you have an image of the current state of the organ then, just as if you did an x-ray image of something. unless you need to check up on the organ for some reason, you do NOT need to repeat the procedure. the patient will be non-radioactive within about three days, with most of the radioactivity being excreted within 24 hours.

Hab gelesen, die allgemeine Strahlungsbelastung für normale Bürger sollte bei ca 4 mSv/Jahr liegen(2mSv/Jahr durch Natürliche Quellen und weitere Zwei durch Künstliche, bei Untersuchungen). Bei Zwei Tagen mit 1mSv/std ergibt das im Vergleich gewaltige 48 mSv in dieser relativ kurzen Zeit, also das 12-Fache dieser angegeben Jahresdosis. Da hätte ich dann schon Grund zur Sorge, wenn ich solch eine Untersuchung auch nur mehrmals innerhalb 10 Jahren durchführen müsste.

theoretisch schon, praktisch zerfaellt das zeug aber 1. sehr schnell (halbwertszeit 6 stunden) UND wird sehr schnell ueber die nieren ausgeschieden... insofern, wenn man nicht am technetium-tropf ;) haengt, betraegt die effektive dosis gerade mal 1 mSv.

what's the difference between technetium 99 and 99m?

when an atom decays (alpha / beta), the daughter nucleus is usually in an excited stage and thus, emits a gamma ray. in most cases, this happens RIGHT after decay (a few nanoseconds after it). however, in some cases, it takes longer for the gamma ray to emitted - and this is the case after Mo-99 decays into Tc-99. the newly formed Tc-99m atom takes an average (half life) of 6 hours to emit the y-ray. this is called a METASTABLE state, and that's what the "m" stands for. :)

so yeah, to sum it up, Tc-99m is the metastable state that has NOT yet emitted the gamma ray; the half life for the gamma emission to happen is 6 hours. Tc-99 is the ground state after having emitted the gamma ray of excitation energy from the Mo-99 decay, and it has a half life of twohundredthousand years. it then undergoes beta-decay to form Ru-99, which is stable (not radioactive).
